Abstract
This paper analyses the conditions required to eliminate the trial runs during the balancing of large flexible rotors. These conditions include: the identification of the principal axes of stiffness, the determination of the rotor mode shapes and modal masses, and the extraction of the modal parameters from the measured vibration data, for each critical speed considered during the balancing. The paper also discusses possible reasons why modal balancing without trial runs has not been incorporated to field balancing practice.
